10.5.1 Parallel Interface (‘G’ Version Only)
The PC’s IEEE1284 Parallel Port has several operating modes. The default is “Compatibility Mode” which emulates the
original Centronics Parallel Interface. Depending on the PC’s Operating System the Compatibility Mode can provide adequate
(Win 98/ME) or marginal (Win2K/XP) data delivery rate. Using printer firmware V1.02 (or later) in conjunction with the
Printer Driver V2.02 (or later) permits Parallel Port ECP mode operation. (Note: ECP, with DMA, must be selected in the
PC’s BIOS). When the PARALLEL INTERFACE selection is set to “ECP MODE” the printer will negotiate with the host PC
and operate in this high data rate transfer mode. If the PARALLEL INTERFACE selection is set to Compatibility mode the
printer will not negotiate with the host PC to go into ECP mode. This setting disables ECP MODE and enables Compatibility
mode.
10.5.2 Low Paper Cable Detection
If your printer is equipped with the Low Paper Sensor that has Active Cable Detection (4
th
quarter 2004), then, by
setting the LP CABLE DETECT to “ACTIVE” it will enable two actions:
-1- the connected status (connected or disconnected), of the Low Paper cable, will be reported in the printer’s status
information (refer to the Programmer’s Guide).
Note: an older Low Paper senor, w/o the Active cable detection capability will always “appear”
to be disconnected if the LP CABLE DETECT is set to “ACTIVE”.
-2- If the Low Paper cable is disconnected, the Printer’s Low Paper condition will be forced and reported in the
printer’s Low Paper status information (refer to the Programmer’s Guide).
Setting the LP CABLE DETECT to “PASSIVE” it prevents old Low Paper sensor from being reported as disconnected yet
permits the new Low Paper cables to be detected as connected
